Abstract
Spätestens mit Beginn des 21. Jahrhunderts findet die inhaltliche Erschließung von Dokumenten praktisch ausschließlich in digitaler Form statt. Dies gilt sowohl für die fachliche Inhaltserschließung durch Bibliotheken und andere Dokumentationseinrichtungen als auch für die verschiedensten Formen inhaltlicher Beschreibung in Datenbanken - von Produktbeschreibungen im Internethandel bis zum Social Tagging. Selbst dort, wo analoge Ursprünge vorhanden sind, beispielsweise handschriftliche Notizen oder retrokonvertierte Findmittel, liegt die Sacherschließung am Ende in Form von Daten vor. Für die konkrete Ausprägung dieser Daten gibt es allerdings viele verschiedene Möglichkeiten. Der vorliegende Beitrag soll einen Überblick darüber geben, wie unterschiedliche Praktiken der Datenverarbeitung die Qualität von Inhaltserschließung beeinflussen und wie die Qualität von Erschließungsdaten beurteilt werden kann. Der Fokus liegt also nicht auf den Inhalten von Erschließungsdaten, sondern auf ihrer Form. Die Form von Daten ist keine rein technische Nebensächlichkeit, sondern durchaus relevant: So ist eine inhaltlich hervorragende Erschließung unbrauchbar, wenn die Erschließungsdaten aufgrund inkompatibler Datenformate nicht verwendet werden können. Zur qualitativen Einschätzung von Inhaltserschließung ist es daher notwendig, sich auch darüber im Klaren zu sein, wie und in welcher Form die Erschließungsdaten verarbeitet werden.
